Alarm Retarding Devices - ANSThis is required to prevent false alarms when the check calve clapper is lifted from its seat by temporary pressure surge.. All Handles of Indicating valves - ANS(PAINTED RED, GREEN, YELLOW) These handles control controlling the water supplies to the standpipe and sprinkler systems. Automatic DRY Sprinkler Systems - ANSinstalled where a wet pipe system cannot be heated to prevent freezing. Under normal conditions there is no water in the piping. when a sprinkler head is opened by the heat from a fire, the air pressure is reduced in the piping. The drop in air pressure causes a special dry pipe valve to open. Automatic Standpipe System - ANSA standpipe system that is attached to a water supply capable of supplying the system demand at all times and that requires no action other than opening a hose valve to provide water at hose connections. Automatic WET Sprinkler Systems - ANSAutomatically distribute water on a fire, rise in temperature to a predetermined level causes the sprinkler head to open, about 96% of fire areas are extinguished or controlled when sprinklers are installed, they signal a existence of a fire , the downward force of the water sprayed from the sprinklers lowers the smoke level in the room.

Booster pumps/special service pumps - ANSThe booster pump is usd when the water pressure available at the highest sprinkler head does not quiet meet the needs of the sprinkler system Build up on Foreign Material on Sprinklers - ANSThis build up is commonly called loading. Replace all loaded (painted) sprinkler heads. Dust deposits can be blown off. Bulb Sprinkler - ANSA sprinkler operated by heat breaking a glass bulb filled with a non-freezing liquid with diamiter that vary from 3mm for quick response sprinklers to 5mm for standard response sprinklers. Churning - ANSA condition in a centrifugal in which the impeller is rotating, but no water is being discharged. Combination Standpipe and Sprinkler System - ANSA system where the fire protection piping services both 21⁄2 in. (65 mm) outlets for fire department use and outlets for automatic sprinklers. Combination Standpipe and Sprinkler System - ANSA system where the water piping service both 2 1/2in (65) outlet for fire Department use and oulet for automatic sprinkler Common Deficiencies - ANSThe Most common sprinkler system deficiencies include painted or loaded sprinkler heads, building contents located less than 18 inches below sprinkler deflectors. Glass bulb sprinklers are sensitive to damage and required to be to be shipped from the factory with protection.

system. The Valve is automatically opened when a fire protection system discovers that there is a fire or smoke condition. Pressure Maintenance Pumps (Jockey Pumps) - ANSPressure maintenance pumps, Some times referred to as jockey, or makeup pumps, are often found on sprinkler systems. These pumps are designed to automatically operate when there is a slight drop in pressure due to the leakage in the system or a pressure surge. The jockey pump restores the pressure in the fire protection system to the desired level. When the drop of pressure in the system greater than the capacity of the jockey pump the fire pump is activated. Pressure Reducing Valve - ANSA valve or device designed for the purpose of reducing of reducing the downstream water pressure under flowing (residual) conditions only.

Tank contents to be maintained at one third air to two thirds water. Pressure Tank Alarms - ANSThe alarm system automatically monitors the air to water volume ratio which should always be 1(air) to 2(water) Principle of Operation - ANSThe water available to the centrifugal pump must always be under

pressure because the pump cannot lift water for the supply source. A water tank can be used if the tank supplies the pump due to gravity. In other words the weight of the water forces the water to flow into the pump. Protection of Sprinkler Systems - ANSAll parts of a automatic system exposed to freezing temperatures shall be protected from freezing. Pump Activation - ANSThese controllers activate the pump when there is a drop of water pressure or water flow in the fire protection system.
